(Cl. 4-l99) 1 Claim.

My present invention relates to waste and overflow outlets for baths,sinks, basins and the like, and more particularly to an improvedcombined waste and overflow outlet fitting.

My present invention, while designed primarily for use in connectionwith baths, sinks or other commercial personal convenience receptacles,where it is necessary or desirable to have not only a waste outlet but aWaste overflow outlet, is adapted for use in connection with anyreceptacle for holding fluids and where an eflicient and convenientcombined waste and overflow outlet fixture is desirable or necessary.

In carrying out my present invention, I preferably make the combinedwaste and overflow outlet; fitting as an entity separate from thereceptacle with which it is to be associated, and arrange the overflowoutlet fitting either as a'unitar'y structure or as a plurality ofelements making up a structure having the individual elements 5adjustable relatively to each other, and wherein the operating mechanismfor the waste outlet valve may be inserted within and convenientlyhoused in the waste and overflow outlet.

The object of my invention therefore is an improved waste and overflowoutlet fitting for a container for water or other fluid.

A feature of my invention resides in the inclusion within the waste andoverflow outlet fitting of a waste outlet valve of the shear gate type.

A further feature of my invention is an improved waste and overflowoutlet fitting adaptable for bottom or lateral discharge therefrom.

Various other features of the invention will appear as the descriptionof the invention progresses.

In the accompanying drawing:

Fig. 1 is a vertical sectional elevation of the waste and overflowoutlet and of a container for fluids to which my present invention hasbeen applied, the structure embodying the invention being shown insectional elevation;

Fig. 2 is a front elevation of the structure shown in Fig. 1, and

Fig. 3 is a mere elevation partly broken away in section of the shaftand overflow outlet fitting shown in section in Fig. 1.

I have illustrated in the drawing two embodiments of my invention, eachillustrating the use of a shear gate valve in connection with the wasteoutlet opening of a fluid container. One embodiment also illustrates alateral discharge outlet from the waste and overflow outlet fitting, andthe other embodiment a bottom discharge. Further, in one embodimentwaste and overflow outlet fitting is built up of a plurality of'elements, all adjustably associated with each other, and in the otherembodiment the waste and overflow outlet fitting is a relatively massivehollow casting, and this also contains the shear gate type of wasteoutlet valve.

Referring to the drawing, and particularly to Figs, 1, 2 and 3, l0designates the waste and overflow outlet end of a container, such as abath, sink or the like for water or other fluids and in which there isarranged at the bottom thereof a Waste outlet opening II and adjacent tothe top thereof a waste outlet opening [2. There is associated with thewaste outlet opening I I a waste outlet valve to be presently described,and which when closed, will permit fluid, such as water, to be keptwithin the container Ill and until the height of such fluid rises abovethe lower edge of the overflow outlet opening I 2. This overflow outletopening ordinarily is always open and therefore it acts as a spillway topermit excess of fluid to flow out of the container In.

I have associated my present invention with the above described wasteand overflow outlets l I and I2 respectively. In the drawing, I3designates an overflow outlet fitting having an internally threadedorifice l4 therein and which is adapted to receive the externallythreaded end I 5 of a combined bearing and strainer member IS. A washerll, of preferably resilient material such as rubber, is employed asshown in Figure 1 to assist in maintaining a fluid-tight joint betweenof the invention the I the member 5 and the internally threaded openingof the fitting I3. The lower end l8 of the fitting I3 is substantiallycylindrical and is counterbored to receive as a snug sliding fit theupper end of a tubular member I 9 of any suitable length and whichtubular member extends downwardly to a point adjacent to but above thewaste outlet H.

Associated with the Waste outlet II is a fitting 20 substantiallytubular in form and provided with a passage 2| extending therethroughand when the fitting 20 is in position relative to the waste outlet IIthe passage 2| registers with the waste outlet ll. Formed integral withthe fitting 20 and within the passage 2| is a boss 22'drilled and tappedto receive the threaded end of a headed bolt 23. One end of the fitting20 is contoured to the shape and form of the lowercorner of thecontainer ID, as shown in Fig. 1, and interposed between the contouredend of the fite ting 29 and the container I!) is a gasket 24 of anysuitable material.

As shown, the material of the container l surrounding the waste outletII is contoured to provide a recess in which is seated a strainer 25 insuch a manner that the surface of the strainer lies substantially flushwith the inner surface of the container ID, This strainer 25 is providedwith a perforation through which extends the body portion of thethreaded bolt 23, and it will be apparent that as the bolt 23 is screwedinto the boss 22, the fitting 20 will be brought into close andfluid-tight association with respect to the waste outlet I l of thecontainer I6.

Associated with the free end of the fitting 20, and with the lower endof the tubular member I9, is a fitting 26 which may be of any suitablematerial and preferably is of metal. As shown in Figure 1 the fitting 26is hollow and its upper end is internally recessed to receive the lowerend of the tubular member [9, and the exterior of the upper end isthreaded to receive the internal threads of a packing nut 21 On theupper end of the fitting 26 and within the packing nut 21 is resilientpacking 28 which, when the packing nut 21 is screwed onto the fitting26, assists in maintaining a fluid-tight joint between the fitting 26and tubular member IS.

The fitting 26 in alignment with the fitting 20 is provided with apassage through which the cylindrical end of the fitting 20 extendsterminat ing at a point within the fitting 26. This end of the fitting26 is externally threaded to receive the threads of a packing nut 29which in association with the packing 30 serves to maintain afluid-tight joint between the fitting 26 and fitting 29. The fitting 26is provided with a threaded outlet 3l for connection to any desiredwaste line.

On the interior of the fitting 26 and on each side of the cylindricalend of the fitting 20 is formed a guideway 32, These guideways are inalignment with each other and form a track on which a shear gate valve33 may slide, the downward movement of the shear gate valve beinglimited by the open end of the passage 2| in the fitting 20. The sheargate valve 33 has the face 34 thereof thus coacting with the end of thepassage 2| which acts as a valve seat (see Figure 1).

On the shear gate valve 33 is a stud or shaft 35 on which is pivotallymounted the lower end of a connecting rod 36. The upper end of theconnecting rod 36 is pivotally mounted on a shaft 31 which is anintegral part of a shaft 38.

The shaft 31 is parallel to such shaft 38 and is offset therefrom. Theshaft 38 is rotatably mounted in a bearing 39 formed integral with thecombined strainer and bearing member l6. The shaft 38 has secured at itsend an operating handle 40 and by means of which the shaft 38 may berotated in the bearing 39 to rotate the shaft 31 about the same as acenter and thus cause an upward or downward movement of the shear gatevalve 33.

The fittings I3 and 20, when secured to the container ill in the mannerabove described, determine the ultimate position of the fittings 26 andI9, but it is quite apparent that a considerable degree of flexibilityas regards a fitting or adjustment is permitted by the manner ofassociating the various fittings together. Also should it be desired, itis quite possible to remove the fitting l3, or the fitting 20, and someof the associated fittings without disturbing the seating or adjustmentof the fitting l3 with respect to the container l0.

Whereas I have described my invention by reference to specific formsthereof, it will be understood that many changes and modifications maybe made without departing from the spirit of the invention. I

I claim:

An improved waste and overflow outlet for receptacles for liquid and thelike and in which there is provided a recess surrounding the overflowoutlet, comprising in combination, a hollow waste and overflow outletfitting, means for attaching one end of said outlet fitting to theoverflow outlet of the receptacle, a bearing centrally located in theattaching means, a combined bottom outlet and attaching means forsecuring said outlet fitting to the bottom outlet of the receptacle,said latter attaching fitting including a shear gate'valve seat locatedinteriorly of the outlet fitting and also including a strainer contouredto fit within the recess in the receptacle and with the outer surface ofsuch strainer lying flush with the interior surface of the receptacle,means passing through the strainer for clamping the outlet fitting ontothe receptacle, a shear gate valve associated with the valve seat, ashaft provided with a crank arm rotatably mounted in the aforesaidbearing, connecting means extending between the crank arm and the saidshear gate valve, and a lever attached to the outer end of the shaft,and within the confines of the receptacle, for operating said valve.
